CONNECTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 645,618, dated March 20, 1900.

i nanon filed January 19,1899- seri 7 (No model To ctZZ whom it may concern.-

Be it known that I, JOHN R. CARTER, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Connecting Devices; and I do hereby declare the following to be a full, clear, and exact description of the invenv pitmen that they can be quickly and removably connected with a rotating part and be normally prevented from escape.

A further object is to provide means whereby two arms can be removably connected with a shaft and be disposed at an angle to each other without danger of escape from said shaft.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figures 1', 2, 3, and 4 are enlarged views illustrating my improvements, and Fig. 5 is a view showing one application of my invention.

WVhile my improvements are applicable to machinery of various kinds, I have, for the sake of convenience, shown them as applied to a washing-machine.

A represents the tub or receptacle of a washing-machine,andB the cover thereof. A lower rubber O is mounted to oscillate in the receptacle A and cooperates with an upper rubber D, also mounted to oscillate (in a reverse direction) in said receptacle. A crankshaft 1 is mounted on the cover of the receptacle A and connected by a pitman E with the lower rubber 0. Another pitman F is connected at one end with the crank-arm 2 of said shaft and at the other end with an arm 0, projecting upwardlyfrom the upper rubber. It is to the connection between these pitmen and the crank-shaft that my present invention has particular reference.

The arm or pitman E is provided at its end with a hook 3, adapted to be placed on the crank-arm of the shaft 1, and in rear of said hook the arm or pitman E is provided on one or both sides with a tooth or projection 4 to bear against the hook-shaped end of the other arm or'pitman F and prevent the escape of the latter from the crank-shaft. The arm or pitman F is bifurcated to form two hooks 5 5 In connecting the pitmen with the shaft they will first be placed in line with each other, so that all the hooks will aline, as shown in Fig. 1, and be thus adapted to be placed on the shaft. The arm or pitman F will then be turned and made to assume an angle to the arm or pitman E, when both arms or pitmen will be efiectually connected with the shaft without danger of escape therefrom during the rotation of the shaft.

The arms or pitmen are capable of a wid range of movement relatively to each other without danger of becoming detached from the shaft, and yet they can be readily and quickly removed and replaced, which is a feature of importance in packing and shipping machines of the character on which my improvements are adapted to be used.

Myimprovements may also be used for supporting a revoluble shaft, in which case'the arms E F would be secured at their ends opposite the hooks to any suitable support.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isp 1. In a pitman-coupling, the combination with a shaft, of two arms or pitmen remov ably mounted at one end thereon, one arm or pitman having an open hook for the reception of the shaft and having shoulders at respective sides of the base of said hook, the other arm havinga pair of open hooks mount ed on the shaft and embracing the first-mentioned hook, said pair of hooks ders on the arm or pitinan having the single prevented hook, said shoulders located at the base of from displacement by the shoulders on the said single hook and adapted to receive said arm having the single hook.

2. In a pitmanconpling, the combination with a shaft, of two arms or pitmen, on'ehaving a single open hook and the other having a pair of open hooks, the single hook disposed on the shaft with the open end up and the pair of hooks disposed on the shaft so as to em brace the single hook and V-shaped shoulpair of hooks.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOHN R. CARTER.
